The type of error in the sentence is the incorrect placement of the adverb clause. The definition of a symphony is a long piece of classical music and therefore the best place for the adverb clause would be at the end,after the main clause . The correct sentnce is:
<em>A symphony is a long piece of classical music where many kinds of instruments play.</em>
